Improperly installed shake roof wears prematurely
Oct 27, 2017 6:00 AM - Q. When my home was 4 years old, I installed a wood shake roof over the original asphalt shingles. That was about 20 years ago. I was told the shakes would last about 30 years, but many of them are already badly rotted. My contractor says this is because the asphalt shingles should have been removed before installing the shakes.
